The invention relates to new types of modulators of the cold menthol receptor TRPM8, methods for modulating the TRPM8 receptor using these modulators; in particular the use of the modulators for inducing a sensation of coldness; and also the articles and compositions produced using these modulators.

BACKGROUND OF THE INVENTION

The cold menthol receptor TRPM8 (also referred to as Cold Membrane Receptor (CMR)1) belongs to the family of the “Transient Receptor Potential Ion Channels”, is specifically expressed in a special group of neurons and, in the cell membrane, forms pores (in each case 4 units combine to give a tetramer), which selectively allow Ca²⁺ ions to pass. The protein has 6 transmembrane domains and a cytoplasmatic C and N terminus. Low temperatures (preferably 10-25° C.) stimulate this receptor, resulting in a signal transduction which is interpreted by the nervous system as a sensation of coldness. The receptor was described for the first time in 2002 as cold receptor in a number of publications (Peier A M et al, A TRP channel that senses cold stimuli and menthol. Cell. 2002 Mar. 8; 108(5):705-15; McKemy D D et al. Identification of a cold receptor reveals a general role for TRP channels in thermosensation Nature 2002 Mar. 7; 416 (6876): 52-8; Zuker C S. Neurobiology: A cool ion channel Nature 2002 Mar. 7; 416 (6876): 27-8).

Cooling compounds, such as e.g. menthol, have for a long time played an important role in the flavorings and fragrance industry in order to produce an association with freshness and cleanliness. For the compound menthol, it has been shown that it acts as a natural modulator of the receptor TRPM8 (McKemy D. D., Molecular Pain 1, 2005, 16; McKemy D. D., Nature 416, 2002, 52-58; Peier A. M., Cell 108, 2002, 705-715; Dhaka A., Annu. Rev. Neurosci. 29, 2006, 135-161). By applying menthol, TRPM8 is activated, which brings about a Ca²⁺ influx into the cold-sensitive neurons. The electrical signal produced as a result is ultimately perceived as a sensation of coldness.

Elevated menthol concentrations lead to irritation and an anesthetic effect. Moreover, various publications have described menthol derivatives with a similar effect (British Patent 1971 #1315761 Watson H. R., J. Soc. Cosmet. Chem. 29, 1978, 185-200; Furrer S. M., Chem. Percept. 1, 2008, 119-126). There are also individual compounds, structurally unrelated to menthol, which bring about a significant TRPM8 modulation, such as e.g. Icilin (Wei E. T., J. Pharm. Pharmacol. 35, 1983, 110-112; WO 2004/026840), WS-23 or compounds listed in the patent application WO 2007/019719.

Further effects of substances which modulate the TRPM8 receptor and/or its insect analogs are a repellent effect on insects (WO 2002/015692; WO 2004/000023, US 2004/0028714), and also activity in antitumor therapy (e.g. an influencing of prostate tumors), activity in the treatment of inflammatory pain/hyperalgesia and an effect as TRPM8 antagonists in the treatment of bladder syndrome or overactive bladder (Beck B. Cell Calcium, 41, 2007, 285-294; Levine J. D. Biochim. Biophys. Acta, Mol. Basis Dis. 1772, 2007, 989-1003; Mukerji G., BMC Urology 6, 2006, 6; US 2003/0207904; US 2005/6893626, Dissertation Behrendt H. J. 2004, Universitat Bochum; Lashinger E. S. R. Am. J. Physiol. Renal Physiol. Am J Physiol Renal Physiol. 2008 Jun. 18. [Epub ahead of print]; PMID: 18562636).

However, many of the TRPM8 modulators found hitherto have deficiencies with regard to strength of effect, duration of effect, skin/mucosa irritation, odor, taste, solubility and/or volatility.

The international patent application WO 2010/026094 by the applicant proposes individual specific compounds for modulating the TRPM8 receptor. These comprise the following specifically disclosed compounds:

where the compound may be present in chemically pure or enriched form, as individual stereoisomer or in the form of stereoisomer mixtures. Moreover, WO 2011/061330 from the applicant describes three new types of substance classes of generic TRPM-8 modulators.

There continues to be a need for further substances for modulating the TRPM8 receptor; in particular substances for inducing a sensation of coldness on skin and mucosa.

SUMMARY OF THE INVENTION

It was therefore an object of the present invention to identify novel substances, which lead to a modulation of the TRPM8 receptor, which can be used as alternatives to the modulators known hitherto. Such compounds should in particular also be suitable for applications in the field of cosmetics (e.g. hair care, skin care, oral care), nutrition (feed/food), textiles, OTC products (e.g. burn ointment), pharmaceuticals (e.g. tumor treatment, bladder weakness) or packagings.

DETAILED DESCRIPTION OF THE INVENTION 1. Definitions 1.1 General Terms

In the literature there are various synonyms for “TRPM8”: TRPP8, LTRPC6, CMR1, MGC2849, transient receptor potential cation channel subfamily M member 8. Within the context of the present invention, all names are encompassed. Also encompassed are all functional modifications of the receptor, such as, in particular, splice variants, isoforms, such as e.g. TRPM8 CRA_a, TRPM8 CRA_b and all analogous receptors from various organisms, such as human, mouse, rat. The nucleotide and amino acid sequences of the various receptors are known per se and listed in sequence databases. Thus, e.g. the sequence information for hTRPM8 is entered under the number NM 024080.

Within the context of the invention, a “modulator” is a compound which can act as agonist and/or antagonist of the TRPM8 receptor in vivo and/or in vitro, in particular in vivo.

Suitable modulators here can act either only as antagonist or agonist, in particular only as agonist, or both as antagonist and also as agonist. Here, in particular an agonistic or an antagonistic effect can be established depending on the particular modulator concentration selected.

Here, an “agonist” is a compound which mediates an activation of the TRPM8 receptor, 5 thus induces a Ca²⁺ ingress into the cold-sensitive neurons and thereby mediates a sensation of coldness. By contrast, an “antagonist” is a compound which can counteract this activation of the TRPM8 receptor.

The mediators according to the invention can exert their effect by binding reversibly or irreversibly, specifically or nonspecifically to a TRPM8 receptor molecule. Usually, the binding takes place noncovalently via ionic and/or nonionic, such as e.g. hydrophobic, interactions with the receptor molecule. Here, “specific” encompasses both exclusive interaction with one or more different TRPM8 receptor molecules (such as e.g. TRPM8 molecules of different origin or various isoforms). By contrast, “nonspecific” is an interaction of the modulator with a plurality of various receptor molecules of different function and/or sequence but where, as a consequence, a desired agonistic and/or antagonistic modulation (as described above) of the TRPM8 receptor can be established.

In this connection, “standard conditions” in a cellular activity test for modulators according to the invention is understood as meaning an activity test carried out with HEK293 cells which have been transformed with human TRPM8 and loaded with calcium-sensitive dye (such as e.g. Fluo-4AM, i.e. fluo-4-acetoxymethyl ester), subsequent addition of the test compound and detection of the color change, the experimental procedure taking place at 37° C.; as described e.g. in reference example 3 below, or in Behrendt et al (2004) loc. cit.).

A “modified form” or “derivative” of a modulator according to the invention is also referred to as “functional analog” or “functionally equivalent compound”, particularly if they furthermore exhibit the desired biological activity (receptor-TRPM8 modulation). Within the context of the invention, “derivatives” are also compounds which permit a coupling of the specifically disclosed substances to solid carriers; a large selection of corresponding linker/spacer groups is known to the person skilled in the art. The derivatization can take place here prior to the coupling to a solid phase or only as a result of the coupling.

A modulator according to the invention serves in particular to induce a sensation of coldness in humans and/or animals. An “induction of a sensation of coldness” is present when the compound in the cellular activity test described above exhibits an agonistic effect on hTRPM8.

Besides the customary constituents for the particular composition, compositions according to the invention comprise an “effective amount” of at least one modulator according to the invention. In this connection, “effective” means a concentration of the modulator which suffices to bring about the desired effect, such as e.g. pharmacological effect, or sensory effect, such as the olfactory effect of coldness, upon application of the composition (e.g. application to the skin).

A “topical” application encompasses in particular cutaneous or oral application forms.

Unless specified otherwise, according to the invention, all compounds mentioned herein in all of their isomeric or stereoisomeric forms, as pure substance or as a mixture of isomeric and/or stereoisomeric forms are encompassed.

4. Further Embodiments of the Agents According to the Invention

4.1 General Details Regarding Fields of Application and Formulations of Active Ingredients According to the Invention

The active ingredients according to the invention have a broad field of application in human cosmetics and care, in particular skincare and haircare, but can also be used pharmacologically, and also in foods and textile products, but can also be used as repellents and as a constituents of insecticidal compositions.

The compositions according to the invention may be in particular skin cosmetic, hair cosmetic, dermatological, hygiene or pharmaceutical compositions. In particular the active ingredients according to the invention, in particular active ingredients with a cooling effect, are used for skin cosmetics and/or hair cosmetics or as mouth care compositions.

The haircare or skincare preparations according to the invention are in particular in the form of an emulsion, a dispersion, a suspension, in the form of an aqueous surfactant preparation, a milk, a lotion, a cream, a balm, an ointment, a gel, granules, a powder, a stick preparation, such as e.g. a lipstick, a foam, an aerosol or a spray. Such formulations are highly suitable for topical preparations. Suitable emulsions are oil-in-water emulsions and water-in-oil emulsions or microemulsions.

As a rule, the hair cosmetic or skin cosmetic preparation is used for application to the skin (topically) or the hair. In this connection, “topical preparations” are understood as meaning preparations which are suitable for applying the active ingredients to the skin in a fine distribution, such as e.g. in a form that can be absorbed by the skin. Of suitability for this purpose are e.g. aqueous and aqueous-alcoholic solutions, sprays, foams, foam aerosols, ointments, aqueous gels, emulsions of the O/W or W/O type, microemulsions or cosmetic stick preparations.

According to one embodiment of the cosmetic composition according to the invention, it comprises a carrier. Preferred carriers are water, a gas, a water-based liquid, an oil, a gel, an emulsion or microemulsion, a dispersion or a mixture thereof. The specified carriers exhibit good skin compatibility. Of particular advantage for topical preparations are aqueous gels, emulsions or microemulsions.

The teaching according to the invention also comprises the use of the active ingredients described herein in pharmaceutical compositions for the treatment of an individual, preferably a mammal, in particular a human being, useful animal or domesticated animal. The active ingredients are administered for this in the form of pharmaceutical compositions which comprise a pharmaceutically compatible excipient with at least one active ingredient according to the invention and optionally further active ingredients. These compositions can be administered, for example, by an oral, rectal, transdermal, subcutaneous, intravenous, intramuscular or intranasal route.

Examples of suitable pharmaceutical formulations are solid medicament forms, such as (fine) powders, granules, tablets, pastilles, sachets, cachets, sugar-coated tablets, capsules such as hard and soft gelatin capsules, suppositories or vaginal medicament forms, semisolid medicament forms, such as ointments, creams, hydrogels, pastes or plasters, and also liquid medicament forms, such as solutions, emulsions, in particular oil-in-water emulsions, suspensions, for example lotions, injection and infusion preparations, eye and ear drops. Implanted release devices can also be used for administering inhibitors according to the invention. Furthermore, liposomes, microspheres or polymer matrices can also be used.

In the preparation of compositions according to the invention, active ingredients according to the invention are usually mixed or diluted with an excipient. Excipients may be solid, semisolid or liquid materials which serve as vehicle, carrier or medium for the active ingredient. The active ingredient content (of one or more simultaneously present active ingredients according to the invention) can vary here within a wide range and is, for example, in each case based on the total weight of the composition, in the ppm range from about 0.05 ppm-<0.1 ppm and 0.1 to 1000 ppm (i.e. 0.00001 to 0.1% by weight), such as e.g. 1 to 800 ppm or 100 to 500 ppm or in the range from 0.1 to 50, 1 to 30 or 2 to 10% by weight.

Suitable excipients include, for example, lactose, dextrose, sucrose, sorbitol, mannitol, starches, acacia gum, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup and methylcellulose. In addition, the formulations can comprise pharmaceutically acceptable carriers or customary auxiliaries, such as glidants, for example tallow, magnesium stearate and mineral oil; wetting agents; emulsifiers and suspending agents; preservatives, such as methyl and propyl hydroxybenzoates; antioxidants; antiirritant substances; chelating agents; sugar-coating auxiliaries; emulsion stabilizers, film formers; gelling agents; odor masking agents; taste correctors; resins; hydrocolloids; solvents; solubilizers; neutralizing agents; permeation accelerators; pigments; quaternary ammonium compounds; refatting and superfatting agents; ointment, cream or oil base substances; silicone derivatives; spreading auxiliaries; stabilizers; sterilants; suppository bases; tablet auxiliaries, such as binders, fillers, glidants, disintegrants or coatings; propellants; drying agents; opacifiers; thickeners; waxes; softeners; white oils.

The first-mentioned is used on account of its thixotropic properties, the second on account of its better effectiveness in eliminating the substances adhering to the dental surfaces. The use of these products ensures a low scouring effect since, they are amorphous solids of average hardness which are simultaneously entirely compatible with the fluoride used as mineralizing agent, since they do not comprise any lime salts which would bring about their insolubility and reduce their bioavailability.

The formulation of the mouthcare compositions according to the invention, such as, for example, toothpaste, can also comprise suitable additives and vehicles in order to improve their properties and to facilitate production. These are selected, for example, from binders, thickeners, fragrances, dyes, preservatives, wetting agents or humectants, surfactants, lubricants, opacifiers, remineralizing substances, surfactants, buffers, alcohols, vitamins, water, additional active ingredients and mixtures thereof.

Organic thickeners may also be incorporated in the mouthcare composition, such as sodium carboxymethylcellulose, cellulose ether, xanthan gum, carrageenans, sodium alginate and carbopols. It is also possible to use inorganic thickeners, such as silicon oxide thickeners, sodium aluminum silicates and clays, for providing the appropriate rheology. The thickener may be present in the formulation in an amount of 0.5-5% by weight of the total amount.

The toothpaste can be aromatized by adding a suitable customary fragrance, e.g. a peppermint aroma. Essential oils including inter alia clove oil, cinnamon oil, peppermint oil and spearmint oil are likewise suitable. The fragrance may be present in the formulation in an amount of 0.5-15% by weight of the total amount.

As dye, any of the dyes customarily used in the production of toothpaste can be used, for example brilliant blue FCF, C.42090 [KIRSCH PHARMA]. The dye may be present in the formulation in an amount of 0.001-0.005% by weight of the total amount.

The wetting agent or humectant used to prevent the toothpaste from drying out and hardening is in particular selected from glycerol, sorbitol, propylene glycol, xylitol and liquid polyethylene glycols, in particular a mixture of sorbitol, glycerol and xylitol, e.g. in an amount of 1-60% by weight of the total amount.

The lubricant may be any of the agents customarily used in the formulation of a toothpaste, e.g. dimethicone (polymer of dimethylpolysiloxane), which is a surface-active agent which contributes to imparting good rheological properties to the toothpaste according to the invention. The lubricant may be present in the formulation in an amount of 0.25 to 0.75% by weight of the total amount.

The opacifier used may be any of the agents customarily used, e.g. titanium dioxide. The opacifier may be present in the formulation in an amount of 0.05 to 1% by weight of the total amount.

The remineralizing agent used is a fluoride source, e.g. sodium fluoride, tin(II) fluoride and sodium monofluorophosphate, since in this way 100% of an active fluoride as agent for remineralizing the white lesions caused by the organic acids which are a consequence of bacterial metabolism. The remineralizing agent may be present in the formulation in an amount of 0.2 to 0.4% by weight of the total amount.

Typically, furthermore customary constituents may be present, such as anionic surfactants, such as e.g. sodium lauryl sulfate, sodium N-laurylsarcosinate, sodium lauryl sulfoacetate and sodium alkyl glyceryl ether sulfonate. The surfactant may be present in the formulation in an amount of 0.05 to 5% by weight of the total amount.

If desired, the toothpaste proposed by the invention can also comprise a vitamin which is selected from the group formed by vitamin A, vitamin B5, vitamin C and vitamin E, Sand mixtures thereof. If used, each vitamin may be present in the formulation in an amount of 0.1 to 5% by weight of the total amount. These vitamins can be used as such, in the form of provitamins or in the form of acceptable pharmaceutical salts. Vitamin A, which is usually used in the form of its palmitate salt, promotes the epithelization of the oral mucosa and protects the gingiva. Vitamin B5, more specifically D-panthenol, has a pain-alleviating, healing and anti-inflammatory effect, protects the epithelial mucosa, promotes the epithelization of injuries and smooths scars; it is suitable for the treatment of injuries which arise as a result of dental extractions, gingivitis, stomatitis, pain after inserting dental prostheses, ulcers, traumatic damage to the mucosa, chronic and declining aphthae. Vitamin C regenerates the epithelium of oral mucosa, promotes the synthesis of collagen and the immune system (inflammatory mechanism) and increases the ability of the phagocytes to protect against bacteria. Vitamin E, which is normally used in the form of its acetate salt, has a pain-alleviating and anti-inflammatory effect, protects the oral mucosa against the over-oxidation of fat as a consequence of the formation of free radicals and against contaminating substances in the environment (ozone, cigarette smoke etc.) and favors the healing of injuries. As a result of adding one or some of these vitamins, the invention offers a toothpaste which, besides the aforementioned properties, also has anti-inflammatory features and pain-alleviating effects which increase the ability of the membranes to protect the oral mucosa and reduce the index of dental film formation and dental tartar formation and also that of bacterial contamination.

Additional active ingredients are, for example, antimicrobial and plaque-penetrating agents, such as beta-naphthol, thymol, chlorothymol and hexylresorcinol; or germicidal compounds, such as quaternary ammonium compounds; tartar control agents, such as tetrasodium pyrophosphate, GANTREZ-Polymer® S-70, sodium tripolyphosphate and zinc citrate; peroxide compounds, such as hydrogen peroxide and inorganic peroxides.

Optionally, a buffer can also be used which is present in concentrations suitable for maintaining a pH of about 6-8, such as e.g. alkali metal phosphate buffer. In addition, the presence of potassium ions exerts an effect alleviating oversensitivity.

Water or alcohol may be present in an amount of 1 to 20% by weight of the total amount of the composition.

In combination with the alcohol or instead of the alcohol, it is also possible to use glycol compounds, such as glycerol, sorbitol or propylene glycol.

The mouthcare composition according to the invention can be prepared easily by mixing suitable amounts of the different constituents in a reactor equipped e.g. with stirring paddles.

4.4. Cooling Plasters

In principle, the active ingredient content can vary over a wide range, such as e.g. 0.00001 to 50% by weight, in particular 0.001 to 10% by weight or 0.005 to 1% by weight.

Plasters according to the invention can be constructed in any desired manner, for example by the matrix system, the membrane system or the nonwoven system (Drug Dev. Ind. Pharm. 14 (1988), 183-209; Drug Dev. Ind. Pharm. 13 (1987), 589-651; Drugs of Today 23 (1987), 625-646).

The matrix system consists in the simplest manner of 3 parts: the flexible protective film, the adhesive matrix comprising the active ingredient and a peelable film. If a nonadhesive matrix is used, an edge zone of the protective film must be provided with adhesive to adhere to the skin.

By contrast, a membrane system has at least 5 parts: a flexible protective film, a reservoir with dissolved or suspended active ingredient, a membrane for controlling the release of active ingredient, an adhesive layer applied to the membrane and a peelable film.

In the nonwoven system, the layer comprising the active ingredient consists of an absorbent nonwoven or porous polymer which is impregnated with an active ingredient solution or suspension. This layer, which is firmly bonded to the protective film, is covered by a peelable film. The edge of the protective film is provided with adhesive for application to the skin.

In principle, all active ingredients according to the invention can be formulated in this way.

The auxiliaries to be used are those customary for producing plasters. Besides the adhesive agent, generally a polymer with a glass transition temperature between −70 and −10, in particular −55 and −25° C., and also a carrier film which is coated with this adhesive agent, and the active ingredient, emulsifiers, thickeners and also substances which are intended to influence the release of the active ingredient, and other auxiliaries are often added.

The adhesive polymers with the aforementioned low glass transition temperatures are known, for example from the U.S. Pat. Nos. 2,973,282 and 3,307,544. The self-adhesive bands and films should stick to human skin upon mere contact, although the cohesion of the adhesive layer and its adhesion to the carrier film should be greater than the adhesion to the skin, so that it can be removed again largely without leaving a residue. These are generally copolymers based on acrylic and methacrylic acid esters of alcohols having 2 to 12, in particular 4 to 8, carbon atoms, which can comprise numerous other comonomers in copolymerized form, for example (meth)acrylic acid, (meth)acrylonitrile, (meth)acrylamide, N-tert-butyl(meth)acrylamide, vinyl esters such as vinyl acetate, vinyl propionate or vinyl butyrate, other vinyl compounds such as styrene, also butadiene. Particular preference is given to butyl acrylate and 2-ethylhexyl acrylate. The polymers can be crosslinked by adding small amounts of comonomers having 2 or more copolymerizable double bonds, i.e. for example of diacrylates, such as butanediol diacrylate, or divinyl compounds, such as divinyl-benzene, or by adding other crosslinking agents, e.g. melamine-formaldehyde resins.

Adhesive polymers which can be used are also polyisobutylenes and polyvinyl ethers of varying molecular weight.

The particle size of the dispersions should be between 50 and 500 nm, in particular between 50 and 200 nm. The particle size and the degree of crosslinking can be adjusted in a known manner depending on the polymerization conditions and the comonomers. Smaller particle sizes and an increased degree of crosslinking can bring about an increase in the release of active ingredient.

Matrix plasters can be produced in the customary manner by dissolving or finely dispersing the active ingredient in a suitable polymer solution and then drawing out this active-ingredient-containing self-adhesive mass by means of roller or knife-coating methods to give the film. In some cases, it is expedient to dissolve or very finely disperse the active ingredient, prior to adding it to the polymer solution, in an organic solvent, e.g. ethanol or acetone. Better distribution of the active ingredient in the polymer can thereby be achieved.

The plasters can also be produced in accordance with the German patent application P 38 07 283.1 by incorporating the active ingredient in finely powdered form (particle size below 200, in particular below 50 μm) into the aqueous latex dispersion, or dispersing or dissolving it in an aqueous emulsifier solution and mixing this mixture into the aqueous latex dispersion at a temperature from 10 to 80, in particular 30 to 70° C. In addition, the salt of an active ingredient in aqueous solution can also be mixed with the polymer dispersion at a pH at which the active ingredient is predominantly present in the water-soluble ionized form. By shifting the pH, the active ingredient is then converted to the uncharged water-insoluble form and simultaneously emulsified into the dispersion.

Expediently, the active ingredient is introduced as initial charge, the emulsifier and water are added and the mixture is then mixed with the polymer dispersion. The active-ingredient-containing dispersion obtained in this way is optionally provided with further auxiliaries and, as mentioned, is drawn out to give a film in a manner known per se on a protective film and dried. The drying temperature here can be between room temperature and 100° C., an optimum between desired rapid drying and bubble formation in the film, which is to be avoided, and also thermal stressing of the active ingredient generally being 35 to 45° C.

This process has the great advantage of avoiding organic solvents. However, in principle, all other customary production processes for matrix plasters are also suitable.

The resulting films have thicknesses of 10 to 800, preferably 50 to 300 μm. The film can be produced continuously or discontinuously. The coating process can be repeated several times until the film has achieved the desired thickness. The adhesive polymer layer comprises the active ingredient in a concentration in the range from 1 to 40, in particular 5 to 25% by weight. The same concentration also applies for the reservoir liquid in the membrane system and for the active ingredient solution or dispersion with which, in the nonwoven system, the nonwoven or the porous polymer is impregnated.

The emulsifiers used both for the active ingredients and also the polymers are the surfactants customary for this purpose, such as the sodium salt of relatively long-chain fatty acids and the sulfuric acid half-ester of an (optionally oxyethylated) fatty alcohol as examples of anionic surfactants, and polyoxyethylated alkylphenols and relatively long-chain fatty alcohols (e.g. hexadecan-(1)-ol) and glycerol fatty acid partial esters as examples of nonionic surfactants and coemulsifiers.

The desired viscosity of the ready-to-draw-out mass can be adjusted e.g. with polyacrylic acids or cellulose derivatives.

Additional crosslinking agents, which improve the cohesion and thus the adhesion properties of the films, that can be used are e.g. melamine-formaldehyde resins.

For the purposes of improving the release of active ingredient, source substances such as polyvinylpyrrolidone, cellulose derivatives or polyacrylates are effective since the film can increasingly absorb water and, as a result, the resistance to diffusion drops.

The release of the active ingredients can be further improved by adding hydrophilic plasticizers such as glycerol, 1,2-propanediol or polyethylene glycols and lipophilic plasticizers such as triacetin, dibutyl phthalate or isopropyl myristate.

Matrix plasters usually produce an active ingredient release of the first order. The use of fillers which adsorb the active ingredient, such as Aerosil, microcrystalline cellulose or lactose, results in approximately a release of zero order.

The protective film onto which the active-ingredient-containing self-adhesive mass is dried is expediently virtually impermeable both for the active ingredient and for water vapor. It can, for example, consist of an aluminum-plastic composite film, a metalized plastic film, a plastic film which is provided with a barrier layer of e.g. polyvinylidene chloride facing the active ingredient side, or of a simple plastic film, e.g. polyester film.

The plasters according to the invention which are constructed by the membrane system are likewise produced in the customary manner (e.g. EP 0 186 071 A2, U.S. Pat. No. 4,262,003).

The plasters constructed by the nonwoven system are produced by impregnating nonwovens or porous polymers attached to the protective film with a solution or dispersion of the active ingredient in a hydrophilic or lipophilic solvent or solvent mixture. The impermeable peelable film is then applied.

For some applications, a preferred protein source is hydrolyzed protein (protein hydrolysate), which is optionally admixed with amino acids.

The protein hydrolysate may be any desired suitable protein hydrolysate which is used in a food, such as soya protein hydrolysate, casein hydrolysate, whey protein hydrolysate, other animal and vegetable protein hydrolysates and mixtures thereof. The protein hydrolysate of the composition according to the invention is preferably a soya protein hydrolysate, whey protein hydrolysate or a casein protein hydrolysate which comprises short peptides and amino acids and is optionally admixed with additional amino acids.

4.6. Textile Products Finished with Active Ingredients According to the Invention.

In principle, the active ingredient content can vary over a wide range, such as e.g. 0.00001 to 50% by weight, in particular 0.001 to 10% by weight or 0.005 to 1% by weight.

The finishing of textiles with active ingredients according to the invention is of interest in many respects.

Thus, the finishing of textiles with cooling compounds is used in particular wherever items of clothing can come into direct contact with the skin, such that the active ingredient can develop its effects, e.g. locally or systemically, through transdermal transfer. In recent times, textiles have been reported which are finished with so-called wellness additives, i.e. substances which promote wellbeing (R. Breier “Megatrend Wellness—Innovative Ideen for die Textilausrostung”, 31. Aachener Textiltage November 2004).

An insecticidal finishing in turn is of interest with regard to material protection, e.g. finishing of the textile to prevent it being eaten by moths etc., but in particular also to repel parasitic insects, such as flies.

A fundamental problem in the finishing of textiles with active ingredients is the binding of the active ingredient to the textile carrier which, on the one hand, must ensure a permanency of the finishing and, on the other hand, must be selected such that the active ingredient does not lose its effect. In this regard, various approaches have been proposed in the prior art.

Thus, e.g. cyclodextrins have been proposed for the binding of active ingredients to textiles (see, for example, DE-A-19810951 and EP-A-0 392 608). Cyclodextrins are cyclic oligosaccharides which are formed by enzymatic degradation of starch. The most common cyclodextrins are α-, β- and γ-cyclodextrins, which consist of six, seven or eight, respectively, α-1,4-linked glucose units. A characteristic property of the cyclodextrin molecules is their ring structure with largely invariable dimensions. The internal diameter of the rings is about 570 μm for α-cyclodextrin, about 780 μm for β-cyclodextrin and about 950 μm for γ-cyclodextrin. On account of their structure, cyclodextrins are in the position of being able to incorporate guest molecules, in particular hydrophobic guest molecules, in changing amounts up to saturation.

EP-A-1710345 describes the finishing of textiles with fragrances and other low molecular weight organic active ingredients via an amylose-containing substance with an amylose content of at least 30% are bonded to the textile. As a consequence of the amylose fractions in the amylose-containing substance, the active ingredient is bonded to the textile and released in a controlled manner, such that the effect is maintained over a long period. It is assumed that the active ingredient is reversibly bonded as in the case of cyclodextrins in the cavities formed by the helical conformation of the amylose in the sense of an inclusion compound, as a result of which, on the one hand, fixing of the active ingredient to the surface of the textile carrier is achieved and, on the other hand, controlled release is possible.

Of suitability for the finishing according to the invention of textiles are, besides amylose, in principle all substances, in particular amylose-containing starches, i.e. native starches, modified starches and starch derivatives, the amylose content of which is at least 30% by weight and—in particular at least 40% by weight. The starch may be native, e.g. corn starch, wheat starch, potato starch, sorghum starch, rice starch or maranta starch, be obtained by partial digestion of native starch or be chemically modified. Pure amylose as such, e.g. enzymatically obtained amylose, e.g. amylose obtained from sucrose, is also suitable. Also of suitability are mixtures of amylose and starch if the total content of amylose is at least 30% by weight, based on the total weight of the mixture. It goes without saying that here and hereinbelow all data in % by weight which refer to amylose or amylose-containing substances in mixtures of amylose and starch are always based on the total weight of amylose+starch, unless expressly stated otherwise.

Of particular suitability according to the invention are amylose-containing substances, in particular amylose and amylose-containing starches and also amylose/starch mixtures whose amylose content is at least 40% by weight and in particular at least 45% by weight, based on the total weight of the substance. As a rule, the amylose content will not exceed 90% by weight and in particular 80% by weight. Substances of this type are known and commercially available. For example, amylose-containing starches are sold by Cerestar under the trade name Amylogel® and National Starch under the trade names HYLON® V and VII.

To achieve the binding of the active ingredient(s) and the textile, the textile can be treated with the amylose-containing substance usually in an amount of at least 0.5% by weight, preferably at least 1% by weight and in particular at least 2% by weight, in each case based on the weight of the textile. As a rule, the amylose-containing substance will be used in an amount of not more than 25% by weight, often not more than 20% by weight and in particular not more than 15% by weight, based on the weight of the textile, so as not to adversely affect the tactile properties of the textile. Firstly, the textile material is finished with the amylose-containing substance as such and then the textile finished in this way is treated with a suitable preparation of the active ingredient. As a result, the amylose-containing substance located on the textile material is loaded with the active ingredient.

However, it is also possible to use the amylose-containing substance together with an active ingredient in order to finish the textile. Here, the active ingredient and the amylose-containing substance can be applied both as a mixture of separate components and in the already prepared form of the amylase-active ingredient complex.

As a rule, the active ingredient will be used in an amount which suffices for the desired effect. The upper limit is determined by the maximum absorption capacity of the amylose units of the amylose-containing substance used and will generally not exceed 20% by weight and often 10% by weight, based on the amylose content of the substance. If desired, the active ingredient is generally used in an amount of from 0.00001 to 15% by weight, 0.0001 to 10% by weight, 0.001 to 5% by weight, 0.005 to 1% by weight or 0.1 to 10% by weight or 0.5 to 5% by weight, based on the amylose content of the amylose-containing substance.

For the textile finishing, it is also possible to use combinations of active ingredients according to the invention with other active ingredients known per se and suitable for the finishing of textiles.

Suitable further active ingredients are in principle all organic compounds and mixtures of organic compounds which, are known as active ingredients and which induce a physiological effect in living organisms such as humans and animals, including microorganisms. Mention may be made of those active ingredients which are known to be able to form inclusion compounds with cyclodextrins. Of particular suitability are active ingredients which have hydrocarbon groups and in particular aliphatic, cycloaliphatic and/or aromatic structures. The molecular weight of the active ingredients is typically below 1000 daltons and often in the range from 100 to 600 daltons. Moreover suitable are inorganic compounds such as hydrogen peroxide, which as are known can be bonded into cyclodextrins (see in this regard F. Vögtle, Supramolekulare Chemie [Supramolecular Chemistry], 2^(nd) edition, B. G. Teubner, Stuttgart 1992, Cyclodextrins and literature cited therein).

The further active ingredients include in particular pharmaceutical active ingredients and active ingredients which promote the wellbeing of living organisms, in particular of humans, and which are generally also referred to as “wellness additives”. In contrast to pharmaceutical active ingredients, the wellness additives do not necessarily have to have a therapeutic effect. Rather, the effect promoting wellbeing can be based on a large number of factors such as care, stimulating, cosmetic or other effects. Similarly of suitability are organic active ingredients which are effective against parasitic organisms. These include, for example, active ingredients which are effective against fungi and/or microorganisms, e.g. fungicides and bactericides, or which are effective against animal pests such as slugs and snails, worms, mites, insects and/or rodents, e.g. nematicides, molluscicides, insecticides, acaricides, rodenticides and repellent active ingredients, and also furthermore active ingredients to combat weeds, i.e. herbicides, or fragrances.

Preferred pharmaceutical active ingredients are those which are known to be able to be absorbed by the skin. These include, for example, ibuprofen, fluorbiprofen, acetylsalicylic acid, acetamidophen, apomorphine, butylated hydroxytoluene, chamazulene, guaiazulene, chlorthalidone, cholecalciferol, dicumarol, digoxin, diphenylhydantoin, furosemide, hydroflumethiazide, indomethacin, iproniazid phosphate, nitroglycerol, nicotin, nicotinamide, oubain, oxprenolol, papaverine alkaloids such as papaverine, laudanosine, ethaverine and narcotin, and also berberine, also retionol, trans-retinoleic acid, pretinol, spironolactone, sulpiride, theophylline, theobromine, corticosteroids and derivatives such as testosterone, 17-methyltestosterone, cortisone, corticosterone, dexamethasone, triamcinolone, methylprednisolone, fludrocortisone, fluocortolone, prednisone, prednisolone, progesterone, including estrogens and gestagens such as estradiol, estriol, ethynylestradiol 3-methyl ether, norethisterone and ethisterone, and also phenethylamine and derivatives such as tyramine, adrenalin, noradrenalin and dopamine.

To improve the washing permanency of the finishing according to the invention, it has proven useful if the amylose-containing substance is fixed to the textile using a binder. Suitable binders are firstly film-forming, water-insoluble polymers and, secondly, low molecular weight reactive substances which polymerize upon heating. As a rule, the binder will be used in an amount such that the weight ratio of amylose-containing substance to water-insoluble polymer is in the range from 1:1 to 100:1, preferably in the range from 1.5:1 to 50:1 and in particular in the range from 2:1 to 20:1.

As a rule, the film-forming polymers are used in the form of an aqueous dispersion of finely divided polymer particles. The particle size is of minor importance for the success according to the invention. However, it is usually below 5 μm (weight-average) and is generally 50 nm to 2 μm.

The film-forming polymer can in particular have a glass transition temperature T_(G) in the range from −40 to 100° C., preferably −30 to +60° C., in particular −20 to +40° C. If the polymeric binder comprises a plurality of polymer components, at least the main constituent should have a glass transition temperature within this range. In particular, the glass transition temperature of the main constituent is in the range from −30° C. to +60° C. and particularly preferably in the range from −20° C. to +40° C. Preferably, all of the polymeric constituents have a glass transition temperature within these ranges. The stated glass transition temperatures refer here to the “midpoint temperature” determined in accordance with ASTM-D 3418-82 by means of DSC. In the case of crosslinkable binders, the glass transition temperature refers to the uncrosslinked state.

Examples of suitable film-forming polymers are based on the following polymer classes:

-   (1) polyurethane resins -   (2) acrylate resins (straight acrylates: copolymers of alkyl     acrylates and alkyl methacrylates); -   (3) styrene acrylates (copolymers of styrene and alkyl acrylates); -   (4) styrene/butadiene copolymers; -   (5) polyvinyl esters, in particular polyvinyl acetates and     copolymers of vinyl acetate with vinyl propionate; -   (6) vinyl ester-olefin copolymers, e.g. vinyl acetate/ethylene     copolymers; -   (7) vinyl ester-acrylate copolymers, e.g. vinyl acetate/alkyl     acrylate copolymers, and vinyl acetate/alkyl acrylate/ethylene     terpolymers;

Such polymers are known and commercially available, e.g. polymers from classes (2) to (7) in the form of aqueous dispersions under the names ACRONAL, STYROFAN, BUTOFAN (BASF-AG), MOWILITH, MOWIPLUS, APPRETAN (Clariant), VINNAPAS, VINNOL (WACKER). Aqueous polyurethane dispersions (1) suitable for the method according to the invention are, in particular, those which are used for the coating of textiles (see e.g. J. Hemmrich, Int. Text. Bull. 39, 1993, No. 2, pp. 53-56; “Wässrige Polyurethan-Beschichtungssysteme” [Aqueous polyurethane coating systems] Chemiefasern/Textilind. [Chemistry Fibers/Textile Ind] 39 91 (1989) T149, T150; W. Schrber, Textilveredelung [Textile finishing] 22, 1987, pp. 459-467). Aqueous polyurethane dispersions are commercially available, e.g. under the trade names Alberdingk® from Alberdingk, Impranil® from BAYER AG, Permutex® from Stahl, Waalwijk, the Netherlands, from BASF SE or can be prepared by known processes, as are described, for example, in “Herstellverfahren für Polyurethane” [Preparation processes for polyurethanes] in Houben-Weyl, “Methoden der organischen Chemie”, [Methods of organic chemistry], Volume E 20/Makromolekulare Stoffe [Macromolecular substances], p. 1587, D. Dietrich et al., Angew. Chem. 82 (1970), p. 53 ff., Angew. Makrom. Chem. 76, 1972, 85 ff. and Angew. Makrom. Chem. 98, 1981, 133-165, Progress in Organic Coatings, 9, 1981, pp. 281-240, and Römpp Chemielexikon [Chemistry lexicon], 9th edition, volume 5, p. 3575.

The film-forming polymers can be self-crosslinking, i.e. the polymers have functional groups (crosslinkable groups) which, upon drying the composition, optionally upon heating, react with one another, with the functional groups of the amylose or with a low molecular weight crosslinker with bond formation.

Examples of crosslinkable functional groups comprise aliphatically bonded OH groups, NH—CH₂—OH groups, carboxylate groups, anhydride groups, capped isocyanate groups and amino groups. A polymer will often be used that also has free OH groups as reactive groups. As a rule, the fraction of the reactive functional groups is 0.1 to 3 mol/kg of polymer. The crosslinking can be effected within the polymer by the reaction of complementary-reactive functional groups. Preferably, the crosslinking of the polymer is effected by adding a crosslinker which has reactive groups which are complementary to the functional groups of the crosslinker with regard to their reactivity. Suitable pairs of functional groups which have a complementary reactivity are known to the person skilled in the art. Examples of such pairs are OH/COOH, OH/NCO, NH₂/COOH, NH₂/NCO and M²⁺/COOH, where M²⁺ is a divalent metal ion such as Zn²⁺, Ca²⁺, or Mg²⁺. Examples of suitable crosslinkers are the diols or polyols specified below for the polyurethanes; primary or secondary diamines, preferably primary diamines, e.g. alkylenediamines, such as hexamethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, N, N-bis[(aminopropyl)amino]ethane, 3,6-dioxaoctanediamine, 3,7-dioxanonanediamine, 3,6,9-trioxaundecanediamine or Jeffamines, (4,4′-diaminodicyclohexyl)methane, (4,4′-diamino-3,3-dimethyldicyclohexyl)methane; amino alcohols, such as ethanolamine, hydroxypropylamine; ethoxylated di- and oligoamines; dihydrazides of aliphatic or aromatic dicarboxylic acids, such as adipic dihydrazide; dialdehydes, such as glyoxal; partially or completely O-methylated melamines, and also compounds or oligomers which, on average, have two or more, preferably three or more, isocyanate groups or reversibly e.g. hydrogensulfite blocked isocyanate groups. In this case, the quantitative ratio of crosslinker to polymeric binder is such that the molar ratio of the reactive groups in the polymeric binder (total amount of the reactive groups in the polymers) to the reactive groups in the crosslinker is generally in the range from 1:10 to 10:1 and preferably in the range from 3:1 to 1:3. Usually, the weight ratio of polymeric binder (calculated as solid) to crosslinker is in the range from 100:1 to 1:1 and in particular in the range from 50:1 to 5:1.

As an alternative to fixing the amylose-containing substance with water-insoluble polymers, the amylose or the amylose-containing substance can also be fixed to the textile material with reactive compounds which have at least one group which is reactive towards the OH groups of the amylose, and at least one further functional group which is reactive towards the functional groups on the fibers of the textile material, e.g. OH groups, NH₂ groups or COOH groups. The reactive compounds include the aforementioned crosslinkers, and also the substances proposed in DE-A 40 35 378 for the fixing of cyclodextrins, e.g. N-hydroxymethyl and N-alkoxymethyl derivatives of urea or urea-like compounds, such as dimethylolurea (bis(hydroxymethyl)urea, di(methoxymethyl)urea, dimethylolalkanediol diurethanes, such as N, N-dimethylolethyleneurea (N,N-bis(hydroxymethyl)imidazolin-2-one), N,N-dimethyloldihydroxyethyleneurea (N, N-bis(hydroxymethyl)-4,5-dihydroxyimidazolin-2-one), dimethylolpropyleneurea and the like. Materials of this type are commercially available in the form of aqueous formulations for the finishing of textiles, e.g. under the trade names Fixapret® and Fixapret®-eco from BASF SE. The reactive materials which can be used for fixing the amylose-containing substance to the textile material include in particular also compounds with 2, 3, 4 or more (optionally reversibly blocked) isocyanate groups, specifically the polyisocyanate prepolymers based on polyether urethanes and polyester urethanes and reversibly blocked with bisulfite or CH-acidic compounds or oximenes, e.g. butanone oxime, which are described in DE 2837851, DE 19919816 and the earlier European patent application 03015121. Products of this type are also commercially available, for example under the trade names PROTOLAN®367 and PROTOLAN®357 from Rotta GmbH, Mannheim.

To fix the amylose-containing substance, the procedure known for the fixing of cyclodextrins can also be used in an analogous way, in which the cyclodextrin or in the present case the amylose-containing substance is provided with reactive anchors, for example by reacting it with dicarboxylic acids or dicarboxylic anhydrides, such as maleic acid, fumaric acid, maleic anhydride, succinic acid, succinic anhydride or adipic acid, with diisocyanates, e.g. toluene diisocyanate, isophorone diisocyanate, tetramethylene diisocyanate or hexamethylene diisocyanate, or with aminocarboxylic acids in a manner known per se in such a way that only one of the functionalities present in these compounds reacts with the OH groups of the amylose-containing substance and the other is retained for the binding to the reactive groups of the fiber material. Reactive anchors can be generated on the amylose-containing substance also by reaction with 1,3,5-trichlorotriazine, 2,3-dichloroquinoxaline-5,6-carbanoyl chloride, and also with chlorodifluoropyrimidine.

For fixing the amylose, it is also possible to use alkoxysilanes, such as diethoxydi-methylsilane, dimethoxydimethylsilane, triethoxyphenylsilane, tetraethoxysilane, and also dimeric, trimeric and higher condensation products of these compounds.

In this way, it is possible in principle to finish all textile materials, i.e. non-made-up goods and also made-up goods. Textile materials comprise here and below wovens, weft knits, warp knits and nonwovens. The textile materials can be constructed from natural fiber yarns, synthetic fiber yarns and/or mixed yarns. Suitable fiber materials are, in principle, all of the fiber materials customarily used for producing textiles. These include cotton, wool, hemp fibers, sisal fibers, flax, ramie, polyacrylonitrile fibers, polyester fibers, polyamide fibers, viscose fibers, silk, acetate fibers, triacetate fibers, aramid fibers and the like, and also mixtures of these fiber materials.

The finishing or treatment of the textile materials with the amylose-containing substance can be carried out in a manner known per se, e.g. by means of the method described in DE-A 4035378 for the finishing of textiles with cyclodextrins.

Mention may be made, for example, of methods in which the amylose-containing substance, optionally as a complex with the active ingredient, has already been spun into the fiber, the filament and/or the yarn from which the fabric is produced.

However, the textile material will often be treated with the amylose-containing substance or a complex of amylose-containing substance and active ingredient before or after making-up. For this purpose, the textile will as a rule be treated with an aqueous liquor which comprises the amylose-containing substance and optionally the active ingredient in an adequate amount. Depending on the type of application and the desired amount in which the amylose-containing substance is to be applied, the concentration of amylose-containing substance in the liquor is in the range from 1 to 40% by weight, in particular in the range from 2 to 20% by weight and specifically in the range from 4 to 15% by weight.

The type of treatment is of minor importance and can be carried out, for example, as minimal application, e.g. by spray application, as standard application in the padder or as high-moisture application. In this process, the textile material is saturated with the aqueous liquor. Optionally, excess liquor can then be removed, e.g. by squeezing off to a liquor pick-up of about 30 to 120%.

Another option for treating the textile with amylose-containing substance or complex of amylose-containing substance and active ingredient is to prepare a liquor with water, in which the desired amount of amylose-containing substance and optionally active ingredient is present, e.g. 0.5 to 20% by weight (based on the mass of the textile to be finished). The textile material is drenched through over a certain period, e.g. 10-60 min with the treatment liquor in finishing assemblies suitable for this purpose (e.g. winch beck; roller beck; paddle; etc.) and then squeezed off and/or spun off as stated above.

The liquor ratio here is usually in the range from 1:2 to 1:50 and in particular in the range from 1:3 to 1:20.

Methods of this type are known to the person skilled in the art, for example from H. K Rouette, Lexikon der Textilveredlung [Lexicon of textile finishing], Laumann-Verlag, Dülmen 1995, p. 669 ff.

As a rule, the treatment with the liquor is followed by a drying operation. The temperatures here are usually in the range from 100 to 200° C. and preferably in the range from 120 to 180° C. The drying can be carried out in the equipment customary for this purpose, in the case of made-up goods for example by dry-tumbling at the temperatures stated above. In the case of goods which are not made-up, following application, the textile material will usually be guided over one or more tenters.

If the amylose-containing substance is used together with a film-forming polymer, drying leads to a fixing of the amylose-containing substance on the textile fibers. As a rule, the drying temperature will not drop below 100 and is preferably in the range from 120 to 200° C. and in particular in the range from 140 to 180° C. In general, drying takes place over a period of from 1 to 10 min, in particular 1 to 2 min, with longer drying times likewise being suitable.

For the treatment with an aqueous liquor, it has proven advantageous if the aqueous liquor comprises, besides the amylose-containing substance and optionally the active ingredient, at least one surface-active substance (or interface-active substance) which is suitable for dispersing the amylose-containing substance and the active ingredient in the aqueous liquor. The surface-active substance is preferably an oligomeric or polymeric dispersant. The term oligomeric or polymeric dispersant comprises, in contrast to low molecular weight surface-active substances, those dispersants whose number-average molecular weight is generally at least 2000 daltons, e.g. 2000 to about 100 000 daltons and in particular is in the range from about 3000 to 70 000 daltons.

As a rule, the aqueous liquor comprises the polymeric or oligomeric dispersant in an amount of from 0.5 to 20% by weight, preferably 1 to 18% by weight and in particular 5 to 15% by weight, based on the amylose-containing substance.

Suitable oligomeric or polymeric dispersants are soluble in water and comprise both neutral and amphoteric water-soluble polymers and also cationic and anionic polymers, the latter being preferred.

Examples of neutral polymeric dispersants are polyethylene oxide, ethylene oxide/propylene oxide copolymers, preferably block copolymers, polyvinylpyrrolidone, and copolymers of vinyl acetate with vinylpyrrolidone.

The preferred anionic oligomeric or polymeric dispersants are characterized in that they have carboxyl groups and/or sulfonic acid groups and are usually used as salts, e.g. as alkali metal salts or ammonium salts.

Preferred anionic dispersants are, for example, carboxylated derivatives of cellulose, such as carboxymethylcellulose, homopolymers of ethylenically unsaturated C₃-C₈-mono- and C₄-C₈-dicarboxylic acids, e.g. of acrylic acid, of methacrylic acid, of maleic acid, of itaconic acid, copolymers of at least two different ethylenically unsaturated C₃-C₈-mono- and C₄-C₈-dicarboxylic acids as specified above, and copolymers of at least one of the aforementioned ethylenically unsaturated C₃-C₈-mono- or C₄-C₈-dicarboxylic acid with at least one neutral comonomer. Examples of neutral comonomers are N-vinyllactams, such as N-vinylpyrrolidone, vinyl esters of aliphatic C₂-C₁₆-carboxylic acids, such as vinyl acetate, vinyl propionate, amides of the aforementioned ethylenically unsaturated carboxylic acids, such as acrylamide, methacrylamide and the like, hydroxy-C₁-C₄-alkyl (meth)acrylates, such as hydroxyethyl acrylate and methacrylate, esters of ethylenically unsaturated C₃-C₈-mono- or C₄-C₈-dicarboxylic acids with polyethers, e.g. esters of acrylic acid or of methacrylic acid with polyethylene oxides or ethylene oxide/propylene oxide block copolymers, vinylaromatics, such as styrene, and C₂-C₁₆-olefins, such as ethylene, propene, 1-hexene, 1-octene, 1-decene, 1-dodecene and the like. Preference is also given to homopolymers of ethylenically unsaturated sulfonic acids, such as styrenesulfonic acid and acrylamidopropanesulfonic acid and copolymers thereof with the aforementioned comonomers. In the copolymers, the fraction of ethylenically unsaturated acid will usually be at least 20% by weight and not exceed a value of 90% by weight and in particular 80% by weight, in each case based on the total weight of all of the monomers constituting the polymer.

Copolymers of at least one of the aforementioned acids and at least one comonomer are known for this purpose and are commercially available, for example the copolymers of acrylic acid and maleic acid as Sokalan brands from BASF AG.

Likewise preferred anionic dispersants are phenolsulfonic acid-formaldehyde condensates and naphthalenesulfonic acid-formaldehyde condensates (e.g. the Tamol and Setamol brands from BASF) and lignosulfonates.

Dispersants which can be used are also low molecular weight anionic, nonionic, cationic, ampholytic and zwitterionic surfactants. Suitable surfactants are, for example, the alkali metal, ammonium or amine salts of C₈-C₁₈-alkyl sulfates, such as sodium lauryl sulfate; C₈-C₁₈-alkylsulfonates, such as dodecylsulfonate; C₈-C₁₈-alkyl ether sulfates; and also C₈-C₁₈-alkyl ethoxylates; polyoxyethylene sorbitan esters; C₈-C₁₈-alkyl glycinates; C₈-C₁₈-alkyldimethylamine oxides; betaines etc. Preference is given to the alkyl sulfates and alkylsulfonates.

If the amylose-containing substance is not used together with a film-forming, water-insoluble polymer, the textile can be treated with the polymer in a separate working step. In particular, treatment takes place together with the amylose-containing substance. Accordingly, one particular embodiment relates to a method in which the aqueous liquor additionally comprises a dispersed, film-forming, water-insoluble polymer of the type described above. The amount of film-forming polymer is selected such that the weight ratio of amylose-containing substance to water-insoluble polymer is in the range from 1:1 to 100:1, preferably in the range from 1.5:1 to 50:1 and in particular in the range from 2:1 to 20:1.

The finishing of the textile with the active ingredient can take place in a separate operation or in one operation together with the finishing with the amylose-containing substance.

If the textile is finished with the active ingredient in a separate operation, the textile will expediently likewise be treated with an aqueous liquor of the active ingredient. For this, as a rule, the active ingredient, which is usually not soluble in water, will be emulsified or dispersed in water, optionally using suitable surface-active substances. Suitable surface-active substances are in particular the aforementioned low molecular weight surfactants and, of these, preference is given to the nonionic surfactants, in particular polyoxyethylene sorbitan esters, esters of mono- or oligosaccharides with C₈-C₁₈-fatty acids and particularly preferably C₈-C₁₈-alkyl ethoxylates, in particular those with a degree of ethoxylation in the range from 6 to 50. As a rule, the aqueous liquor comprises the active ingredient in an amount of from 0.1 to 10% by weight and in particular in an amount of from 0.2 to 5% by weight. The amount of surface-active substance is generally in the range from 0.5 to 50% by weight and in particular in the range from 3 to 30% by weight, based on the active ingredient. The active ingredient can be applied from aqueous liquor using the methods customary for this purpose, e.g. by means of a padder.

However, it is also possible to carry out the finishing with active ingredient and amylose-containing substance in one operation. The procedure here is in principle as described for the finishing with the amylose-containing substance, except the aqueous liquor of the amylose-containing substance now additionally comprises the at least one active ingredient. The active ingredient here can be added separately to the liquor or in the form of an inclusion compound, i.e. in the form of a host/guest complex with the amylose-containing substance.

The method according to the invention can be used for the finishing of any desired textiles, including wovens, knits, nonwovens and the like. The type of textile material is governed primarily by the desired intended use.

The textiles to be finished may be ready-made products such as clothing, including underwear and outer clothing, such as e.g. shirts, trousers, jackets, outdoor, trekking and military finishings, roofs, tents, nets, e.g. nets to protect against insects and curtains, hand towels and bath towels, bedding and the like.

In the same way, the finishing on the raw goods can take place in pad or roller application form.

The textiles finished with active ingredients against parasitic organisms such as insects and acaricides are suitable not only for protection of human beings, but also particularly in animal protection to protect against ticks, mites, fleas and the like.

The textile materials can be constructed from natural fiber yarns, synthetic fiber yarns and/or mixed yarns, the fabric usually having a weight per area in the range from 10 to 500 g/m², preferably 20 to 250 g/m². Suitable fiber materials are in principle all fiber materials customarily used for producing textiles. These include cotton, wool, hemp fiber, sisal fibers, flax, ramie, polyacrylonitrile fibers, polyester fibers, polyamide fibers, viscose fibers, silk, acetate fibers, triacetate fibers, aramid fibers and the like, and also mixtures of these fiber materials. Also suitable are glass fibers, and also mixtures of the aforementioned fiber materials with glass fibers, e.g. glass fiber/Kevlar mixtures.

Using an amylose-based active ingredient finishing described above, the active ingredients remain in the textiles finished therewith even after several washes.

Moreover, the textiles finished in this way are characterized by a pleasant handle, which is advantageous particularly for the wear comfort of clothing produced from these textiles.

4.7 Cooling Tobacco Products

In principle, the active ingredient content can vary over a wide range, such as e.g. 0.00001 to 50% by weight, in particular 0.001 to 10% by weight or 0.005 to 1% by weight.

The active ingredients according to the invention can advantageously also be used for producing tobacco products. Examples of such tobacco products comprise cigars, cigarettes, pipe tobacco, chewing tobacco and snuff tobacco.

The production of tobacco products which are supplemented with cooling additives is known per se and described e.g. in U.S. Pat. Nos. 3,111,127, 5,752,529 and US 2005/0000529, to which reference is hereby expressly made.

4.8 Cooling Packaging Materials

The active ingredients according to the invention are also advantageously suitable for producing packaging materials.

The production here likewise takes place in a manner known per se. The active ingredients can be incorporated here into the packaging material in free or e.g. encapsulated form, or be applied to the packaging material in free or encapsulated form.

Thus, correspondingly finished plastic packaging materials can be produced according to the details in the literature for producing polymer films (e.g. Ullmann, 6th ed. 2003. Vol. 36, p. 567). The production of papers coated in a suitable manner is likewise known and described e.g. in Ullmann, Vol. 25, p. 106 ff, 6th ed, 2003.

6. Specific Applications

The following specific section of the invention relates to the use of compounds according to the invention (TRPM8 receptor modulators) for producing a long-lasting physiological cooling effect on skin or mucosa.

Physiological cooling active ingredients are regularly used in order to bring about a cool sensory impression on the skin and/or mucosa, for example on the mucosa in the oral cavity, nasal cavity and/or throat cavity, although in fact no physical cooling, as for example upon the evaporation of solvents, takes place. Physiological cooling active ingredients which can be used are either individual components or mixtures. In this connection, it should be taken into consideration that not all compounds which influence receptors in vitro which are (also) involved in the mediation of a physiological cooling effect actually produce such an effect in vivo on the skin or on mucosa. In particular, such an effect will not always proceed in an identical way. This means, for example, that the intensity of the mediated physiological cooling effect and also the course of the intensity of the cooling effect against time cannot be deduced merely from the fact that a certain compound is an agonist of a receptor involved in the mediation of a sensation of coldness.

The best known physiologically effective cooling active ingredient is L-menthol, although this has a number, of disadvantages, e.g. strong odor impression, high volatility and, at higher concentrations, a bitter and/or sharp intrinsic taste, and/or a skin-irritating effect.

Strong cooling active ingredients have therefore already been sought previously which do not have the disadvantageous properties of L-menthol. Thus, e.g. lactic acid esters of menthol(s) as in DE 2 608 226 and mixed carbonates with menthol(s) and polyols as in DE 4 226 043 and menthone ketals as in EP 0 507 190 have been described.

Menthyl monoesters of dioic acids as in U.S. Pat. Nos. 5,725,865 and 5,843,466 are interesting naturally occurring alternatives, but are unable to achieve the intensity of the cooling active ingredients described previously in sensory tests.

In J. Soc. Cosmet. Chem. 1978, 29, 185-200, the results of a study on ca. 1200 compounds were presented, in which the compounds L-menthanecarboxylic acid-N-ethylamide (“WS3”) and in particular N-(L-menthanecarbonyl)glycine ethyl ester (“WS5”) were found to be the strongest cooling active ingredients. However, coupled with a strong effect, the latter has the disadvantage of being hydrolysis-sensitive and, therefore, of forming the corresponding free acid N^(α)-(L-menthanecarbonyl)glycine, which itself exhibits only a very weak cooling effect. Despite the described detailed investigations, a systematic prediction relating to properties of potential cooling active ingredients, especially with regard to their bitterness and/or their other trigeminal effects, is not possible and is also not described. Thus, although many of the molecules which fall under the class of menthanecarboxamides are strongly cooling, they at the same time frequently exhibit markedly bitter notes (e.g. the menthanecarboxylic acid-N-(alkyloxyalkyl)amides according to JP 2004059474) or are additionally severely irritating (WS5: N-[[5-methyl-2-(1-methylethyl)cyclohexyl]carbonyl]glycine ethyl ester, US 2005/0222256).

N^(α)-(Menthanecarbonyl)alkyloxyalkylamides have been described in JP 2004059474.

However, coupled with a strong cooling effect and high hydrolysis stability, these have the disadvantage of being severely bitter and can therefore not be used in foods or in cosmetic products used for facial care.

Furthermore, menthyl glyoxylates and their hydrates have been described in JP 2005343795 as cooling substances.

Overviews of the cooling active ingredients used and produced hitherto can be found in M. Erman, Perfumer & Flavorist 32(10), 20-35 (2007) and M. L. Dewis in D. J. Rowe, Chemistry and Technology of Flavors and Fragrances, Blackwell Publishing Ltd, Oxford 2005, p. 212-222.

Novel compositions are described hereinbelow which have a particular physiological cooling effect and, as a result, can be used as cooling substances (cooling active ingredients) in foods and/or treats and/or mouthcare products and/or (oral) pharmaceutical preparations and/or cosmetic preparations. The compounds and/or mixtures of compounds to be indicated should preferably exhibit the weakest possible intrinsic taste, in particular taste only a little bitter, if at all, and also be as non-irritating as possible.

The invention relates to compositions, such as e.g. an aroma mixture or foods, oral hygiene agents or pharmaceutical or cosmetic preparation used for enjoyment, comprising one, two, three or more of the compounds selected from compounds according to above tables 1 and 2A to D, where the compound or the compounds is present in a concentration of 0.05 ppm-<0.1 ppm or 0.1 ppm to 50% by weight, based on the total weight of the preparation.

In particular, in the compositions described for this specific aspect of the invention, the compounds to be used according to the invention are present in a (total) concentration of from 0.05 ppm to 50% by weight, based on the total weight of the preparation or of the composition. Here, this range is composed in particular of the following sub-ranges: 0.05 ppm-<0.1 ppm. 0.1 ppm-1000 ppm and 0.1-50% by weight. Preferred concentration ranges, based, on the total weight of the preparation or of the composition, are:

0.05 ppm-10% by weight, 0.5 ppm-5% by weight, 1 ppm-2.5% by weight.

Preference is given to a composition according to the invention, in particular to one according to the specific aspect of the invention, comprising

-   (1) one or more further substances with a physiological cooling     effect, where the further substance and/or one, several or all of     the further substances (i) cause a gustatory effect or (ii) do not     cause a gustatory effect,

and/or

-   (2) one or more aroma substances without a physiological cooling     effect

and/or

-   (3) one or more trigeminally or mouth-washing effective substances     without a physiological cooling effect

and/or

-   (4) (iii) one or

(iv) several compounds which, in the case of (iv), independently of one another or together

additionally cause a taste-modulating effect and/or a trigeminal and/or a mouth-Swashing stimulus.

Such a composition also preferably comprises one or more further substances with a physiological cooling effect without a gustatory effect. This avoids, with the composition according to the invention, for example only aromas with a minty aroma character being able to be obtained.

Very particular preference is given to a composition according to the invention comprising, as constituent (2), one or more aroma substances without a physiological cooling effect and/or, as constituent (3), one or more compounds which, independently of one another or together additionally cause a taste-modulating effect and/or a trigeminal and/or a mouth-washing stimulus, where the trigeminal stimulus is preferably not a physiological cooling effect. In particular, those compositions according to the invention which simultaneously comprise the last-mentioned constituents (2) and (3) have a pleasant cooling effect and a balanced sensory profile coupled with a simultaneously high impact, i.e. a high gustatory first impression.

The specific aspect of the invention preferably also relates to compositions in particular as preparations used for food, oral hygiene or enjoyment, or pharmaceutical or cosmetic preparations which comprise an amount of a compound to be used according to the invention or of a mixture of such compounds to be used according to the invention sufficient to achieve a physiological cooling effect on the skin and/or mucosa.

In particular, the used amount of this compound or of this mixture should suffice to achieve a physiological cooling effect on the mucosa in the oral cavity, nasal cavity and/or throat cavity.

In this connection, reference may be made to the fact that the terms “composition” and “preparation” can be used synonymously. However, it is preferred that a preparation must be produced by means of a working step which goes beyond the mere mixing of the individual compounds. Such a working step can serve, for example, to generate a suspension or an emulsification.

Preferred preparations according to the invention comprise 0.000005% by weight to 20% by weight, preferably 0.00001 to 10% by weight, particularly preferably 0.0001% by weight to 0.5% by weight, of compounds to be used according to the invention, based on the total weight of the preparation. Further, constituents, in particular constituents (1) (further substances with a physiological cooling effect), (2) (aroma substances without a physiological cooling effect) and/or (3) (trigeminally or mouth-washing effective substances without a physiological cooling effect) (as described above), and also further customary basic substances, auxiliaries and additives can be present in amounts of from 0.0000001 to 99.99% by weight, preferably 10 to 80% by weight, based on the total weight of the preparation. In addition, the preparations according to the invention can comprise water in an amount up to 99.99% by weight, preferably 5 to 80% by weight, based on the total weight of the preparation.

Particular preference is given to a composition according to the invention where at least one of the compounds selected from the compounds of the above tables 1 and 2A to D.

Preferably, the compounds to be used according to the invention, or their mixtures, are used for producing a drug which serves to control or alleviate the symptoms of coughing/sneezing, oral inflammation, nasal inflammation, throat inflammation or pharyngeal inflammation, throat pain or hoarseness.

Further nonlimiting examples of possible preparation routes of compounds according to the invention of the formulae IA, IB, IC, IA′, IB′ and IC′ are summarized in the following schemes.

in which R₁₁ to R₁₇ can have the meanings given above.

Here, the isoquinoline, the acetylalkene (optionally in molar excess) and a suitable catalyst (e.g. methylammonium chloride) are introduced into a suitable solvent (e.g. ethanol) and stirred at a suitable temperature (e.g. reflux). When the reaction is complete, the catalyst is generally separated off by crystallization from a suitable solvent/solvent mixture (e.g. iPrOH/water). Optionally, for this, a distillative solvent change is necessary beforehand.

in which R₁₁ to R₁₇, X, Y and Z can have the meanings given above, in particular in which X, Z═O, S and Y═—CH2-CH2-, —CH2-CH2-CH2-, CH2-C(CH3)2-CH2-

The aminoketone is firstly converted to the corresponding salt in a suitable solvent (e.g. MTBE) or solvent mixture and an excess of a suitable acid (e.g. hydrochloric acid) and then reacted with the corresponding dialcohol, dithiol or thioalcohol. As a rule, the mixture is then worked-up by aqueous extraction and the product is isolated by distillative removal of the solvent. If further purification is required, this can take place by crystallization from a suitable solvent or by chromatography.

in which R₁₁ to R₁₇, X, Y and Z can have the meanings given above, and e.g. R₁₁, R₁₂═H or these two radicals, together with the carbon atoms to which they are bonded, form a carbocyclic ring having 5, 6 or 7 carbon atoms.

The synthesis of the tri- or tetracyclic analogs of the ketones V3 or V4 ideally starts from an anhydride B1 and a p-amino acid B2 which, as shown in the sterically demanding preparation example H1-20, can be reacted by stirring the two substances at a suitable temperature to give compounds of type B3. To synthesize a phosphorane B5, the acid group of a compound B3 is activated by conversion to the acid chloride or an anhydride and then reacted with a phosphorane B4 to give a compound B5. The resulting ester function is decarboxylated in the subsequent step and the released phosphorane is cyclized in a Wittig reaction to give an unsaturated ketone B6. Finally, ketalization is carried out with acid catalysis with a dithiol, diol or thioalcohol to give a compounds B8 where, depending on the reaction conditions, an addition product B9 can also be formed. If, after work-up by extraction, further purification is required, this can take place by crystallization from a suitable solvent or by chromatography.

in which R₁₄ to R₁₇, X, Y and Z can have the meanings given above.

The ketone is admixed with an excess of dithiol, diol or thioalcohol and an acid or Lewis acid (e.g. zinc chloride) while adding a water-withdrawing agent (for example 4 Å molecular sieve, magnesium sulfate). The reaction mixture is stirred at a suitable reaction temperature and then generally worked-up by aqueous extraction. If a further purification is required, this can take place by crystallization from a suitable solvent or by chromatography.

in which R₁₄ to R₁₇, X, Y and Z can have the meanings given above.

The preparation of analogs to P14 and P15 proceeds in accordance with the following literature procedures, and also the procedures given in the experimental section. (Here no longer detailed explicitly):

A. M. Islam, R. A. Raphael, J. Chem. Soc. 1955, 3151-3154. Bosch, Joan; Rubiralta, Mario; Moral, Montserrat; Arino, Joaquin. Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1986), (8), 1533-9. M. Chiurato, S. Routier, Y. Troin, G. Guillaumet, Eur. J. Org. Chem 2009, 3011-3021

The O,O-acetal analogs to P14 and P15 can be converted to the corresponding thioketals as follows: the oxygen ketal is dissolved in a solvent (e.g. dichloromethane) 15 and admixed with an excess of the dithiol or thioitlycohol, and a Lewis acid (eg. boron trifluoridediethyl etherate). The reaction mixture is stirred at a suitable reaction temperature and then generally worked-up under neutralizing conditions in an aqueous environment. If, after removing the organic solvent, further purification of the products is required, this can take place by crystallization from a suitable solvent or by column chromatography.

The coumarin carboxylate and an excess of 1-cycloalk-1-enylvinyloxytrialkylsilane (e.g. the trimethylsilane compound) are dissolved in toluene or another suitable organic solvent and stirred at a suitable reaction temperature (e.g. reflux). To cleave off the trialkylsilyl group, an excess of a fluoride, e.g. tetrabutylammonium fluoride, is added and the mixture is further stirred at a suitable temperature (e.g. room temperature). (Alternatively, the acid-catalyzed cleavage of the silylenol ether to the ketone is also possible.) In this connection, it may prove to be necessary to replace the solvent used hitherto for a more suitable solvent such as THF by distillation beforehand. Alternatively, the acid-catalyzed cleavage of the silylenol ether to the ketone is also possible. When the reaction is complete, work-up is generally by means of aqueous extraction. If, after removing the organic solvent, further purification of the products is required, this can take place by crystallization from a suitable solvent or by column chromatography.

The keto ester is admixed with an excess of dialcohol, dithiol or thioalcohol, an acidic catalyst (e.g. Amberlyst 15) and a suitable solvent (e.g. toluene) and the mixture is stirred at a suitable temperature (e.g. reflux). Optionally, it proves necessary to remove water from the reaction mixture by adding a water-withdrawing agent (e.g. 4 Å molecular sieve) or azeotropic distillation. When the reaction is complete, work-up is generally by means of aqueous extraction. If a further purification of the products is required after distillatively removing the organic solvent, this can take place by crystallization from a suitable solvent or column chromatography.

Synthesis Route 4:

In stage a), in accordance with the principle of a Reformatsky reaction, the aromatic ketone is converted with bromine-substituted carboxylic acid ester in the presence of zinc into the unsaturated aromatic ester intermediate (cf. e.g. S.

The reaction product from stage a) is saponified, converted to the acid chloride and then amidated, as described in WO 2011/61330 for structure type 3 therein.

Synthesis Route 5:

The reaction of the aromatic 1-keto carboxylic acid according to stage a) takes place in a manner known per se. It is described for various reactants in the prior art (cf. e.g. Xiao, Y., 2009 chemical communications, 3594-3596; Li, H. et al., Organic Letters 2009, 4176-4179; Chen Y.-F. et al., 2010 Advanced Synthesis and Catalysis 352, 7, 1163-1168; Wang, H. et al., Tetrahedron letters 2005, 46, 6, 963-966; Bunce, R.

Various methods for carrying out stage b) are likewise known from the prior art (cf. e.g. Gompper, R, et al., Chemische Berichte, 1981, 114, 8, 2866-2883; Arndt et al., Chemische berichte 1938, 71, 1631-1639; Claisen, Justus Liebigs Annalen der Chemie, 1917, 413, 274). Following saponification and conversion to the acid chloride, an amidation then takes place to give the end product (as described e.g. in: Fürstner, A., et al., 2006, JACS, 128, 24, 8087-8094; Fürstner, A., et al., 2005, JACS, 127, 33, 11620-11621, U.S. Pat.

Synthesis Route 6:

The preparation of α,β-saturated forms of compounds of the general formula III takes place, for example, by targeted reduction of the corresponding unsaturated precursor obtained by one of synthesis routes 1 to 5 (variant a)) (cf. Desai et al., Tetrahedron Lett., 5963-5965, 2001) or by amidation of α,β-saturated carboxylic acid precursors known per se, as described e.g. in WO 2011/61330 for structure type 3 therein, and optionally in the presence of bases, such as NEt₃ (variant b)).

Further aspects of the present invention arise from the examples below and also from the attached patent claims.

Experimental Section

The examples below serve merely to illustrate the invention without limiting it thereto. Unless stated otherwise, all content data are based on the weight. Unless specified otherwise, customary methods known to the respective person skilled in the art in the field of organic synthesis, formulation and biochemistry are used for carrying out the following experiments.

The active ingredients of the formulae I, II and III used according to the invention are either compounds known per se or can be prepared in accordance with known synthesis methods by the person skilled in the art in the field of organic synthesis. Reference is expressly made to the disclosure of the literature references cited herein.

The invention will now be described with reference to the following nonlimiting working examples.

Reference Example 1—Cloning of Human TRPM8

The starting point for the cloning of the human TRPM8 receptor is an LnCaP cDNA library. This is, for example, commercially available (e.g. BioChain, Hayward, USA) or can be produced from the androgen-sensitive human prostate adenocarcinoma cell line LnCaP (e.g. ATCC, CRL1740 or ECACC, 89110211) using standard kits.

The coding TRPM8 sequence (WO 2010/026094; and http://www.ncbi.nlm.nih.gov/entrez/viewer.fcgi?db=nuccore&id=10968964) can be PCR-amplified and cloned using standard methods. The human TRPM8 gene isolated in this way was used for producing the plasmid plnd_M8, the construction of which is illustrated by the plasmid map according to FIG. 2 of WO 2010/026094.

Alternatively to this, the TRPM8 gene can also be produced synthetically.

Reference Example 2—Generation of the HEK293 Test Cells

As test cell system, HEK293 cell line stably transfected with the human TRPM8 DNA (cf. above plasmid plnd-M8) are produced. Preference here is given to HEK293 which offers the option, via the introduced plasmid, of inducing the TRPM8 expression by means of tetracycline.

Methods for producing suitable test cell systems are known to the person skilled in the art. For example, the details of the preparation of the cells used according to the invention can be found in Behrendt H. J. et al., Br J. Pharmacol. 141, 2004, 737-745 or the dissertation by Behrendt “Vergleichende funktionale Untersuchungen des Hitze-Capsaicin-Rezeptors (TRPV1) und des Kälte-Menthol-Rezeptors (TRPM8) in rekombinanten und nativen Zellsystemen”. [Comparative functional investigations of the heat capsaicin receptor (TRPV1) and of the cold menthol receptor (TRPM8) in recombinant and native cell systems], accessible from http://www-brs.ub.ruhr-uni-bochum.de/netahtml/HSS/Diss/BehrendtHansJoerg/diss.pdf.

Reference is expressly made to the disclosure of these documents.

Reference Example 3—Assay on TRPM8 Modulators

A test comparable with the test already described in the literature by Behrendt H. J. et al., Br. J. Pharmacol. 141, 2004, 737-745 is carried out. The agonization or antagonization of the receptor can be quantified by means of a Ca²⁺-sensitive dye (e.g. FURA, Fluo-4 etc.). On their own, agonists bring about an increase in the Ca²⁺ signal; antagonists bring about, in the presence of e.g. menthol, a reduction in the Ca²⁺ signal (in each case detected via the dye Fluo-4, which has different fluorescent properties as the result of Ca²⁺).

Firstly, a fresh culture of transformed HEK cells is prepared in a manner known per se in cell culture flasks. The test cells HEK293-TRPM8 are detached from the cell culture flasks by means of trypsin and 40 000 cells/well are sown out with 100 μl of medium in 96-well plates (Greiner #655948 poly-D-lysine-coated). To induce the receptor TRPM8, tetracycline is added to the growth medium (DMEM/HG, 10% FCS tetracycline-free, 4 mM L-glutamine, 15 μg/ml blasticidin, 100 μg/ml hygromycin B, 1 μg/ml tetracycline). On the following day, the cells are loaded with Fluo-4AM dye and the test is carried out. For this, the procedure is as follows:

-   -   addition of in each case 100 μl/well of dye solution Ca-4 kit         (RB 141, Molecular Devices) to in each case 100 μl of medium         (DMEM/HG, 10% FCS tetracycline-free, 4 mM L-glutamine, 15 μg/ml         blasticidin, 100 μg/ml hygromycin B, 1 μg/ml tetracycline)     -   incubation in the hatching cabinet, 30 minutes/37° C./5% CO₂, 30         minutes/RT     -   preparation of the test substances (various concentrations in         200 μl of HBSS buffer), and also of positive controls (various         concentrations of menthol, icilin and ionomycin in 200 μl of         HBSS buffer) and negative controls (only 200 μl of HBSS buffer)     -   addition of the test substances in amounts of 50 μl/well and         measurement of the change in fluorescence (e.g. in the assay         instrument FLIPR, Molecular Devices or NovoStar, BMG) at 485 nm         excitation, 520 nm emission, and evaluation of the effectiveness         of the various substances/concentrations and determination of         the EC50 values.

The test substances are used in the assay in triplicate in concentrations of 0.1-200 μM. Normally, the compounds are kept ready in DMSO solutions and are diluted down to a maximum DMSO concentration of 2% for the assay.

The evaluation surprisingly reveals that, according to the invention, it was possible for the first time to prepare agonists of TRPM8 which differ significantly in structural terms from agonists known hitherto, such as (−) menthol, icilin and other modulators described by Behrendt H. J. et al., in Br. J. Pharmacol. 141, 2004, 737-745 (cf. table 1 therein), and, moreover, in some cases exhibit better activities than (−) menthol, or are as comparably effective as icilin.

d) Formulation Example FT-1: Textile Finishing with Active Ingredients According to the Invention

Firstly, an aqueous slurry of amylase-containing starch is prepared by admixing 570 g of deionized water with 10 g of a standard commercial preservative. 20 g of carboxymethylcellulose were dissolved therein, then 400 g of an amylase-containing starch with an amylase content of 50% by weight were added and a slurry was prepared with stirring.

Aqueous liquors with amylase-containing starch were then prepared by one of the two following methods:

Method 1: The respective slurry is adjusted to a starch content of 5 or 15% by weight by dilution with water.

Method 2: The respective slurry is firstly diluted to a starch content of 5 or 15% by weight with water and then admixed with 30 g/l of a 30% strength by weight aqueous polyurethane dispersion (nonionogenic).

The finishing of a fabric with amylase-containing starch and active ingredient according to the invention then takes place:

Cotton fabric sample with a weight per area of 124 g/m² is treated with one of the above-prepared liquors using a padder up to a liquor absorption of 80% by weight, based on the weight of the fabric. Drying is then carried out for 2 min at 120° C.

The fabric samples finished in this way are then treated with an aqueous active ingredient formulation by padding an aqueous emulsion/suspension of an active ingredient according to the invention with an active ingredient content of from 1 to 7% by weight onto the fabric sample up to a liquor absorption of 79-80% by weight. The fabric samples treated in this way are then dried in a domestic dryer to a residual moisture of 15%.

The active-ingredient-loaded fabric produced in this way can then be further investigated, such as e.g. as to their cooling effect upon skin contact or their repellent effect on insects.
